LUBRlCATlNG-TROLLEY FOR WIRE-ROPE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 724,203, dated March 31, 1903.

Application filed September 18, 1902. Serial No. 123,876. (No model.)

invented a newand usefulImprovementinLubricating-Trolleys' for Wire-Rope Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to atrolley for lubricating wire-rope railways, in which the oil is drawn up by means of a pump from a receptacle suspended below the ropeand is distributed upon the latter, the pump being worked by means of the trolley-wheels in such -manner that the discharge of oil upon-the rope takes place in proportion to the speed at which the trolley travels.

Wire-rope railways usually have two lines of rope, of which the one is made stronger than the other and serves for the conveyance of the loaded trucks, while the second serves for the return journey of the empty carriages. A lubricating trolley must therefore be arranged to run upon both lines of rope, and in order to serve for the oiling of the light rope it must consequently be constructed as light as possible. With this arrangement, however,it has been found that, in particular when the oil-receptacle is no longer full, the frictional contact between the trolley-wheels and the ropeway is so slight that the one wheel which works the pump frequently skids upon the rope instead of turning, in consequence of which the pump does not work at all.

' The present invention has for its object to obviate this defect without requiring to increase the weight of the trolley for increasing the frictional adhesion of the wheels; and it consists in so arranging the trolley that the pump receives its motion from both the trollay-wheels, whereby each wheel only requires to-supply half the power for working the pump.

A construction of the trolley forcarrying out the said invention is shown on the accompanying drawings, in which- Figure 1 shows a side view of the complete lubricating trolley with its oil receptacle,

while Fig. 2 shows a side view of the trolley i to an enlarged scale.

To the suspension-frame of the lubricatingtrolley is connected the oil-tank a, from which a rotary pump b, arranged between the side cheeks of the trolley, raises the oil through the suction-pipe c in order to discharge it through the delivery-pipe (1 onto the ropeway e. The pump is driven from both the trolley-wheels f, whose axes carry chainwheels g, over which passes a pitch-chain h,'

gearing with a chain-wheel t, fixed on the pump-shaft, by which means the rotation of both trolley-wheels f isimparted to the pump. Experiments have shown that with this arrangement for driving the pump no skidding of the trolley-wheels takes place when the trolley is constructed of the requisite degree of lightness for the weaker ropeway;"'

It is obvious that in place of chain and chain-wheel gear any other suitable gear may In witness whereof I hereunto set my hand in presence of two witnesses.
